Rails: Datetime params are empty? - ruby-on-rails

Question

In my post view, I have a _form with a title and releaseDate parameter.
In my controller I get the value from params[:post][:title], but the params[:post][:releaseDate] is empty.
post _form
<%= form_for(#post) do |f| %>
<% if #post.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#post.errors.count, "error") %> prohibited this post from being saved:</h2>
<ul>
<% #post.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :title %><br />
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :releaseDate %><br />
<%= f.datetime_select :releaseDate %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
posts_controller
def create
#title = params[:post][:title]
#date = params[:post][:releaseDate]
#post = Post.new(title: #title, releaseDate: #date)
#post.user_id = current_user.id
respond_to do |format|
if #post.save
format.html { redirect_to #post, notice: 'Post was successfully created.' }
format.json { render json: #post, status: :created, location: #post }
else
format.html { render action: "new" }
format.json { render json: #post.errors, status: :unprocessable_entity }
end
end
end
(I am not using #post = Post.new(params[:post]) because I want to do something with the title and releaseDate in the controller.)
post.rb (model)
class Post < ActiveRecord::Base
attr_accessible :releaseDate, :title, :user_id
belongs_to :user
end
Any suggestions on how I can get the datetime value from the form and into my controller?

Answer 1

releaseDate is not rails convention, try to rename field to release_date. Maybe this will help.
To proof this concept you can use so called virtual attributes: add release_date getter and setter to model like this (note that logs can help you to narrow down the problem) :
class Post < ActiveRecord::Base
attr_accessible :releaseDate, :title, :user_id
belongs_to :user
def release_date
date = read_attribute('releaseDate')
logger.debug("READ DATE IS #{date} aND CLASS IS #{date.class}") # see this in rails server logs
end
def release_date=(date)
logger.debug("WRITE DATE IS #{date} aND CLASS IS #{date.class}") # see this in rails server logs
write_attribute('releaseDate', date)
end
end
And in view replace all releaseDate with release_date
